Plain English Primary sources Students & tutors

From routine safety to critical change

Learn the reasoning. Follow your local clinical pathway. These are fictional teaching cases, not patient-specific treatment instructions. Adult, pregnancy, pediatric and neonatal responses differ. Use the population-specific pathway and verified weight where required. Use current facility protocols, authorized orders and your scope of practice. Students work under supervision. In a real emergency, activate clinical help rather than consult this page.

How to use these cases Read the cues before opening the actions. Name your first priority, then compare your reasoning. The difficulty describes learning complexity; even an introductory case can involve a serious risk.

Anesthesia recovery & handover

The handover misses a difficult airway

Introductory

The situation

A patient arrives in PACU after a routine-looking procedure. The verbal handover is short, but the anesthetic record mentions difficult intubation and airway swelling. The patient is currently breathing.

What should catch your attention

Airway event not handed over
Current stability can change
Rescue planning matters

Your immediate priority

Ask the anesthesia clinician to clarify the airway event, extubation concerns and rescue plan before leaving.

Decision pathway · a learning summary, not a substitute for the full clinical plan

What the RN should do—and why

1
Respond to the situation first
Ask the anesthesia clinician to clarify the airway event, extubation concerns and rescue plan before leaving. [1]
Why it matters Recovery risk depends on what happened during the procedure, not only the current vital signs.
2
Receive the real handover
Review procedure, anesthetic agents, airway events, medicines, loss, access and specific postoperative risks with the sending clinician. [1]
Why it matters Recovery risk depends on what happened during the procedure, not only the current vital signs.
3
Observe recovery actively
Assess airway patency, breathing, circulation, consciousness, temperature, pain and nausea according to the prescribed pathway. [1]
Why it matters Residual anesthesia and complications can become apparent after arrival.
4
Escalate and verify readiness
Seek anesthesia or surgical review for unexpected findings; use the approved discharge criteria and an individualized destination plan. [1]
Why it matters An acceptable summary score cannot override a serious unresolved clinical concern.

What to look for next

Ensure relevant airway equipment, monitoring and destination instructions match that risk. Review trends after medicines, position changes and transfer; verify the next monitoring and rescue plan.

Avoid this shortcut

Do not accept 'routine recovery' as a complete handover. Do not discharge only because a timer expires or a score improves while airway or circulation remains unsafe.

A clear way to hand it over

“I am calling about this new concern: the handover misses a difficult airway. The key findings are __, starting at __. Baseline and relevant medicines/procedures are __. I have __. My assessment is __, and I need __ by __. Current response and outstanding actions are __.”

Use your facility's handover format; fill in the actual findings and times.

In plain English PACU is the post-anesthesia care unit, where recovery is monitored after anesthesia.

Mobility & fall prevention

The first stand happens too soon

Introductory

The situation

An awake patient asks to walk to the bathroom. Their legs remain weak after regional anesthesia and they become light-headed when sitting up. They dislike using a bedpan.

What should catch your attention

Residual weakness
Postural symptoms
Patient wants independence

Your immediate priority

Stop the unassisted move, offer a dignified safe alternative and reassess recovery before another mobility attempt.

Decision pathway · a learning summary, not a substitute for the full clinical plan

What the RN should do—and why

1
Respond to the situation first
Stop the unassisted move, offer a dignified safe alternative and reassess recovery before another mobility attempt. [1]
Why it matters A fall can happen while staff are trying to finish an otherwise routine activity.
2
Make movement safe
Stay with the person, help them sit or lie safely and call for assistance. Use the assessed transfer equipment and assistance level. [1]
Why it matters A fall can happen while staff are trying to finish an otherwise routine activity.
3
Assess before restarting
Check symptoms, vital signs, medication timing and mobility compared with baseline. Escalate persistent faintness, injury or new neurological signs. [1]
Why it matters The cause may be illness or a medicine effect; an alarm alone does not address it.
4
Update the plan
Arrange an individualized falls and mobility review, explain how to request help and hand over the new assistance needs. [1]
Why it matters Matching supervision and equipment to the person reduces preventable repeat exposure.

What to look for next

Verify strength, sensation, symptoms and approved assisted-mobility criteria. Recheck symptoms and safe transfer ability before another attempt. New chest pain, breathlessness, bleeding or reduced alertness warrants urgent clinical help.

Avoid this shortcut

Do not let embarrassment override fall prevention. Do not continue an unsafe walk, use a blanket restraint or assume dizziness always means dehydration.

A clear way to hand it over

“I am calling about this new concern: the first stand happens too soon. The key findings are __, starting at __. Baseline and relevant medicines/procedures are __. I have __. My assessment is __, and I need __ by __. Current response and outstanding actions are __.”

Use your facility's handover format; fill in the actual findings and times.

Perioperative temperature

Shivering with a low temperature

Introductory

The situation

After a long operation, a patient is shivering and their measured temperature is low. A warming device is available, but the RN also needs to assess breathing, pain and circulation.

What should catch your attention

Measured low temperature
Postoperative heat loss
Shivering adds workload

Your immediate priority

Apply approved warming and review other physiological findings rather than treating shaking alone.

Decision pathway · a learning summary, not a substitute for the full clinical plan

What the RN should do—and why

1
Respond to the situation first
Apply approved warming and review other physiological findings rather than treating shaking alone. [1]
Why it matters Shivering may signal heat loss, but fever and other illness also need recognition.
2
Measure and assess
Use an appropriate temperature measurement and assess comfort, exposure and other causes of shivering or instability. [1]
Why it matters Shivering may signal heat loss, but fever and other illness also need recognition.
3
Warm safely
Use approved warming equipment and warmed fluids when prescribed, checking skin and device instructions. [1]
Why it matters Controlled warming limits heat loss without causing avoidable burns.
4
Review the response
Continue temperature and physiological observations and report persistent abnormality. [1]
Why it matters Hypothermia can affect recovery, coagulation and comfort; failure to improve needs reassessment.

What to look for next

Check temperature trend, comfort and the skin beneath warming equipment. Check temperature trend, shivering, skin safety and hemodynamics; escalating fever or instability needs urgent review.

Avoid this shortcut

Do not give unregulated direct heat or assume shivering always means cold. Do not place an unregulated heat source against the skin or attribute all postoperative shaking to cold.

A clear way to hand it over

“I am calling about this new concern: shivering with a low temperature. The key findings are __, starting at __. Baseline and relevant medicines/procedures are __. I have __. My assessment is __, and I need __ by __. Current response and outstanding actions are __.”

Breathing & oxygen

An oxygen mask has slipped sideways

Introductory

The situation

A recovery patient has prescribed oxygen, but the mask is loose and the observed saturation is falling. They remain awake and can speak. The RN can also see poor probe contact.

What should catch your attention

Oxygen delivery may be ineffective
Probe quality uncertain
Patient assessment remains necessary

Your immediate priority

Assess breathing first, restore the prescribed delivery setup and verify a reliable oximeter signal.

01Oxygen delivery may be ineffective
02Assess breathing first, restore the prescribed delivery setup and verify a reliable oximeter signal.
03Check response + communicate

Decision pathway · a learning summary, not a substitute for the full clinical plan

What the RN should do—and why

1
Respond to the situation first
Assess breathing first, restore the prescribed delivery setup and verify a reliable oximeter signal. [1]
Why it matters A saturation number alone can miss exhaustion, carbon-dioxide retention or poor circulation.
2
Look at the patient
Assess work of breathing, respiratory rate, alertness, perfusion and oxygen saturation with a reliable signal. [1]
Why it matters A saturation number alone can miss exhaustion, carbon-dioxide retention or poor circulation.
3
Support and escalate
Use the prescribed oxygen target and delivery system. Call urgent respiratory help for increasing support needs, drowsiness or distress; prepare ordered blood gases. [1]
Why it matters Targeted oxygen treats low oxygen while blood gases and examination help guide ventilation decisions.
4
Check the equipment and response
Check supply, tubing, fit and connections; reassess symptoms and observations after changes and communicate the trend. [1]
Why it matters A disconnected system and worsening lung disease require different corrective actions.

What to look for next

Confirm recovery toward the prescribed target and investigate persistent abnormality. Watch alertness, respiratory effort and oxygen needs rather than saturation alone. A tiring patient can become quieter while becoming less safe.

Avoid this shortcut

Do not keep increasing oxygen without checking delivery and the patient's ventilation. Do not withhold lifesaving oxygen in critical illness or assume every person with COPD has the same target.

A clear way to hand it over

“I am calling about this new concern: an oxygen mask has slipped sideways. The key findings are __, starting at __. Baseline and relevant medicines/procedures are __. I have __. My assessment is __, and I need __ by __. Current response and outstanding actions are __.”

Use your facility's handover format; fill in the actual findings and times.

Communication & discharge

The medicine explanation is not understood

Introductory

The situation

Before discharge, a patient nods through instructions in a language they understand only partly. They then describe taking two medicines containing the same pain-relief ingredient together.

What should catch your attention

Language barrier
Duplicate ingredient risk
Discharge imminent

Your immediate priority

Use competent language assistance and teach-back to clarify the verified medicine schedule and maximum prescribed limits.

01Language barrier
02Use competent language assistance and teach-back to clarify the verified medicine schedule and maximum prescribed limits.

Decision pathway · a learning summary, not a substitute for the full clinical plan

What the RN should do—and why

1
Respond to the situation first
Use competent language assistance and teach-back to clarify the verified medicine schedule and maximum prescribed limits. [1]
Why it matters Agreement or a smile does not demonstrate understanding of a treatment plan.
2
Make the explanation accessible
Ask the person’s preferred language and communication needs. Use a qualified interpreter for clinical decisions when needed. [1]
Why it matters Agreement or a smile does not demonstrate understanding of a treatment plan.
3
Use a small teach-back
Explain one important step in plain language and ask the person to show or describe it in their own words. [1]
Why it matters This tests how clearly we explained the task without making the person feel examined.
4
Repair the gap
Rephrase, demonstrate and repeat the check. Provide an accessible written plan and a named contact for problems. [1]
Why it matters A usable plan supports safer decisions after the nurse is no longer beside the patient.

What to look for next

Ask the patient to explain the actual home plan and identify whom to call for uncertainty. Confirm the person can identify the next step and warning signs. Resolve missing equipment, support or follow-up before an unsafe discharge proceeds.

Avoid this shortcut

Do not treat nodding or a signed leaflet receipt as evidence of understanding. Do not rely on children to interpret or label a person noncompliant because of a language barrier.

A clear way to hand it over

“I am calling about this new concern: the medicine explanation is not understood. The key findings are __, starting at __. Baseline and relevant medicines/procedures are __. I have __. My assessment is __, and I need __ by __. Current response and outstanding actions are __.”

Anesthesia recovery & handover

Persistent vomiting delays safe discharge

Intermediate

The situation

A patient has repeated vomiting despite initial prescribed treatment. They become dizzy sitting up and have not tolerated oral fluids. The scheduled discharge time is approaching.

What should catch your attention

Repeated vomiting
Poor intake and dizziness
Timer pressure

Your immediate priority

Seek anesthesia review, assess hydration and physiological trends and provide prescribed nausea treatment and fluids.

Why it matters An acceptable summary score cannot override a serious unresolved clinical concern.

What to look for next

Recheck symptoms, safe mobility and individualized discharge criteria. Review trends after medicines, position changes and transfer; verify the next monitoring and rescue plan.

Avoid this shortcut

Do not discharge because the operation was minor or transport has arrived. Do not discharge only because a timer expires or a score improves while airway or circulation remains unsafe.

A clear way to hand it over

“I am calling about this new concern: persistent vomiting delays safe discharge. The key findings are __, starting at __. Baseline and relevant medicines/procedures are __. I have __. My assessment is __, and I need __ by __. Current response and outstanding actions are __.”

Bleeding & circulation

A wound dressing fills with blood again

Intermediate

The situation

A dressing is saturated soon after PACU arrival. It was already changed once. The patient is increasingly pale and tachycardic, though the visible drain volume is modest.

What should catch your attention

Repeated dressing saturation
Physiological change
Drain may not show all loss

Your immediate priority

Call surgical and anesthesia review promptly, quantify visible loss and assess for concealed bleeding.

What the RN should do—and why

1
Respond to the situation first
Call surgical and anesthesia review promptly, quantify visible loss and assess for concealed bleeding. [1]
Why it matters External loss can underestimate bleeding, and a normal early blood count cannot rule out shock.
2
Call and assess
Activate the local bleeding response for instability; assess airway, breathing, pulse, pressure, alertness and visible loss. [1]
Why it matters External loss can underestimate bleeding, and a normal early blood count cannot rule out shock.
3
Prepare safe resuscitation
Maintain or obtain suitable access within competence; prepare ordered fluids, blood tests and blood products using identification and compatibility checks. [1]
Why it matters Resuscitation supports circulation while the team seeks the bleeding source.
4
Track treatment and source control
Report procedure history, anticoagulants and last doses; help arrange urgent specialist review and prescribed monitoring. [1]
Why it matters Replacement alone cannot stop every source of bleeding or resolve medication-related risk.

What to look for next

Track pressure, pulse, wound/drain findings and ordered hemoglobin or coagulation results. Trend observations and loss after interventions. Escalate ongoing shock, respiratory change or a suspected transfusion reaction immediately.

Avoid this shortcut

Do not keep changing dressings without escalating the bleeding pattern. Do not wait for a laboratory result before responding to shock or independently select reversal drugs.

A clear way to hand it over

“I am calling about this new concern: a wound dressing fills with blood again. The key findings are __, starting at __. Baseline and relevant medicines/procedures are __. I have __. My assessment is __, and I need __ by __. Current response and outstanding actions are __.”

Urinary drainage

Urinary retention after spinal anesthesia

Intermediate

The situation

A patient has increasing lower-abdominal discomfort after spinal anesthesia and has not passed urine. They received substantial IV fluid. The RN needs to distinguish retention from low urine production.

What should catch your attention

Bladder discomfort
Recent neuraxial anesthesia
No urine passed

Your immediate priority

Assess bladder fullness using the approved method and seek an authorized retention plan while reviewing fluid status and neurological recovery.

What the RN should do—and why

1
Respond to the situation first
Assess bladder fullness using the approved method and seek an authorized retention plan while reviewing fluid status and neurological recovery. [1]
Why it matters Poor flow can be caused by tubing position, but low output can also reflect serious illness.
2
Check simple causes
Assess pain and bladder symptoms, tubing kinks, bag position and recent urine output; keep drainage unobstructed below bladder level. [1]
Why it matters Poor flow can be caused by tubing position, but low output can also reflect serious illness.
3
Escalate persistent problems
Follow the trained catheter assessment pathway for suspected obstruction, leakage, trauma or retention; obtain a clinical plan. [1]
Why it matters Repeated manipulation or unplanned irrigation can injure tissue and introduce infection.
4
Review the indication
Document output and catheter findings, provide appropriate hygiene and ask whether the catheter is still needed. [1]
Why it matters Removing unnecessary catheters reduces infection risk and supports mobility.

What to look for next

Record measured bladder volume, relief and subsequent urine output. Check relief of bladder symptoms and restored drainage. Fever, bleeding, severe pain or continued low output needs prompt review.

Avoid this shortcut

Do not assume an absent void means kidney failure or insert a catheter without the applicable authorization. Do not disconnect the system to improve flow, routinely irrigate or treat cloudy urine alone as infection.

A clear way to hand it over

“I am calling about this new concern: urinary retention after spinal anesthesia. The key findings are __, starting at __. Baseline and relevant medicines/procedures are __. I have __. My assessment is __, and I need __ by __. Current response and outstanding actions are __.”

Regional anesthesia & neurological change

Pain is rising despite a numb limb

Intermediate

The situation

A patient with a regional block reports worsening deep pain in an operated limb. Movement and sensation remain partly reduced. The dressing looks tight and the expected block pattern is uncertain.

What should catch your attention

Pain despite block
Possible compression
Neurological assessment harder

Your immediate priority

Seek anesthesia and surgical review; compare the block, perfusion and dressing findings and treat disproportionate pain as a warning cue.

Why it matters An expected temporary block and a new neurological emergency can overlap in appearance.
3
Call anesthesia promptly
Report progressive weakness, severe back pain, bladder symptoms or respiratory compromise; stop further local-anesthetic delivery when directed by the emergency pathway. [1]
Why it matters High block, toxicity or compressive complications require expert diagnosis and time-sensitive management.
4
Protect and monitor
Support ventilation as needed within training, prevent falls and prepare ordered neurological assessment or imaging. [1]
Why it matters Safety and repeated observations are necessary while the cause is clarified.

What to look for next

Repeat neurovascular observations and report progression promptly. Trend the distribution and recovery of sensation and movement, with immediate escalation of worsening findings.

Avoid this shortcut

Do not automatically repeat analgesia and attribute the whole problem to block failure. Do not remove a neuraxial catheter or change anticoagulation timing independently, or dismiss progressive deficits as routine block recovery.

Medication safety

An infusion label does not match the handover

Intermediate

The situation

The handover says a low-dose analgesic infusion is running, but the bag label names another medicine. A pump setting alone cannot establish what the patient is receiving.

What should catch your attention

Label-handover conflict
Active infusion
Potential medicine error

Your immediate priority

Stop the unsafe administration step using the emergency/medicine policy, assess the patient and reconcile the preparation and intended order with anesthesia.

1
Respond to the situation first
Stop the unsafe administration step using the emergency/medicine policy, assess the patient and reconcile the preparation and intended order with anesthesia. [1]
Why it matters A familiar-looking package or copied list cannot establish the right medicine for this person.
2
Pause and verify

Why it matters A familiar-looking package or copied list cannot establish the right medicine for this person.
3
Clarify with the team
Contact the prescriber and pharmacist about the discrepancy. Explain urgent omitted-dose risks and obtain a documented safe plan. [1]
Why it matters Both giving the wrong medicine and delaying a time-critical medicine can harm the patient.
4
Close the loop
Record the resolved order, administration decision and monitoring plan; tell the receiving team about any remaining uncertainty. [1]
Why it matters A corrected chart must reach the bedside and the next handover to prevent repetition.

What to look for next

Determine any actual exposure and arrange appropriate monitoring and incident documentation. Watch for adverse effects or effects of a delayed dose according to the medicine. Escalate any deterioration rather than wait for routine pharmacy review.

Avoid this shortcut

Do not relabel the bag from memory or change the rate to make the story fit. Do not guess a dose, crush an unsuitable formulation or silently copy conflicting medication lists.

Changing cognition

New confusion after an apparently smooth recovery

Difficult

The situation

An older patient was orientated before surgery but now alternates between agitation and unusual drowsiness. Pain, urinary retention, hypoxia and medication effects are all possible.

What should catch your attention

Acute change from baseline
Fluctuating attention
Several reversible causes

Your immediate priority

Report the change and assess physiological causes, pain, retention and medicine exposure; use the appropriate delirium assessment pathway.

What the RN should do—and why

1
Respond to the situation first
Report the change and assess physiological causes, pain, retention and medicine exposure; use the appropriate delirium assessment pathway. [1]
Why it matters A quiet, sleepy person can have delirium just as an agitated person can.
2
Find the change
Compare alertness, attention and function with the usual baseline; obtain family observations and assess vital signs and pain. [1]
Why it matters A quiet, sleepy person can have delirium just as an agitated person can.
3
Seek reversible causes
Escalate new confusion; check oxygenation, glucose when indicated, infection clues, medicines, retention, constipation and hydration. Use an appropriate validated assessment if trained. [1]
Why it matters Delirium often reflects illness or several interacting problems rather than worsening dementia alone.
4
Support orientation safely
Use calm explanations, glasses and hearing aids, familiar routines and an individualized safety plan. Involve the clinical team for persistent distress. [1]
Why it matters Supportive care reduces avoidable distress while the cause is investigated and treated.

What to look for next

Compare with baseline and involve a familiar supporter for orientation when appropriate. Trend attention, alertness and physiological observations. Report further decline promptly even if the person is no longer restless.

Avoid this shortcut

Do not dismiss the change as age or give sedation without investigating the cause. Do not dismiss sudden confusion as age, routinely restrain the person or sedate away the warning sign.

What the RN should do—and why

1
Respond to the situation first
Activate urgent clinical assessment and the postoperative ACS pathway, including ECG and prescribed investigations/treatment. [1]
Why it matters Heart ischemia does not always present as a classic crushing chest pain.
2
Recognize the pattern
Assess chest discomfort, breathlessness, sweating, nausea and circulation; call urgent clinical help for concerning or unstable symptoms. [1]
Why it matters Heart ischemia does not always present as a classic crushing chest pain.
3
Prepare time-sensitive assessment
Obtain a prompt ECG and ordered tests, monitoring and access using the local ACS pathway. [1]
Why it matters Early ECG and clinical review guide treatment; one normal tracing does not exclude all ACS.
4
Support ordered treatment
Check allergies, bleeding risk, current medicines and hemodynamics before protocol-directed medicines; prepare transfer if required. [1]
Why it matters Antiplatelet, nitrate and reperfusion decisions depend on diagnosis, contraindications and circulation.

What to look for next

Track symptoms, rhythm and pressure and communicate surgery and bleeding risk to the treating team. Reassess pain, breathing, rhythm and perfusion. Report recurrence or evolving ECG changes even after symptoms settle.

Avoid this shortcut

Do not assume all chest discomfort is positioning pain or independently give a drug with important postoperative contraindications. Do not dismiss symptoms as anxiety, give nitrates despite a contraindication or promise a normal ECG rules out a heart attack.

A clear way to hand it over

“I am calling about this new concern: chest discomfort after non-cardiac surgery. The key findings are __, starting at __. Baseline and relevant medicines/procedures are __. I have __. My assessment is __, and I need __ by __. Current response and outstanding actions are __.”

Why it matters Residual anesthesia and complications can become apparent after arrival.
4
Escalate and verify readiness
Seek anesthesia or surgical review for unexpected findings; use the approved discharge criteria and an individualized destination plan. [1]
Why it matters An acceptable summary score cannot override a serious unresolved clinical concern.

What to look for next

Follow airway effort, consciousness and ventilation, not saturation alone. Review trends after medicines, position changes and transfer; verify the next monitoring and rescue plan.

Avoid this shortcut

Do not leave the patient to fetch a nebulizer or assume a normal saturation proves a safe airway. Do not discharge only because a timer expires or a score improves while airway or circulation remains unsafe.

Stop the transfusion and activate the reaction response, maintaining safe IV access without flushing residual blood. [1]
Why it matters Continuing a harmful transfusion can intensify the reaction.
2
Stop exposure and call
Stop the transfusion, assess airway, breathing and circulation and obtain urgent clinical help. Keep access using the approved pathway without flushing residual blood into the person. [1]
Why it matters Continuing a harmful transfusion can intensify the reaction.
3
Check identity and notify
Recheck patient and product identifiers, notify the transfusion service and retain the bag and tubing for investigation. [1]
Why it matters Identity errors and several serious reaction types need immediate investigation.
4
Support the diagnostic plan
Collect ordered blood or urine samples and monitor observations while the team provides reaction-specific treatment. [1]
Why it matters Breathlessness, shock, fever and pain can have different causes that need different treatments.

What to look for next

Verify identity and send the prescribed samples and product investigation while monitoring ABCs. Trend symptoms and circulation continuously in an unstable reaction. Document product details, volume, onset and actions precisely.

Avoid this shortcut

Do not restart the unit because the patient was already shivering. Do not restart a severe reaction or assume every breathless reaction needs the same fluid or diuretic treatment.

Respond to the situation first
Call emergency help, support airway and ventilation and administer naloxone through the authorized pathway when indicated. [1]
Why it matters Profound sedation and inadequate breathing can lead to arrest even when supplemental oxygen keeps saturation high.
2
Assess breathing immediately
Check responsiveness and normal breathing, stop further opioid delivery and activate emergency support. Start CPR if indicated by the resuscitation assessment. [1]
Why it matters Profound sedation and inadequate breathing can lead to arrest even when supplemental oxygen keeps saturation high.
3
Ventilate and reverse by protocol
Provide airway positioning and trained ventilation support; give naloxone under the authorized pathway without delaying resuscitation. [1]
Why it matters Naloxone can reverse opioid effects, but oxygen alone does not move enough air into the lungs.
4
Watch for recurrence
Continue monitoring and obtain a safe pain and opioid plan from the treating team. [1]
Why it matters The opioid may act longer than naloxone; improvement can be temporary.

What to look for next

Monitor recurrent respiratory depression and arrange the appropriate observation setting. Recheck respiratory effort, consciousness, oxygenation and recurrent sedation. Keep observation and escalation active after an initial response.

Avoid this shortcut

Do not regard sleep and a normal oxygen reading as adequate recovery. Do not leave a drowsy patient alone, rely only on saturation or let naloxone delay CPR.

A clear way to hand it over

What the RN should do—and why

1
Respond to the situation first
Activate the anaphylaxis emergency response and assist first-line epinephrine, positioning and airway/oxygen support under the protocol. [1]
Why it matters A rash may be absent; life-threatening allergy is identified by organ compromise.
2
Recognize severe compromise
Stop the suspected trigger when possible; call emergency help for sudden airway, breathing or circulation problems after an exposure. [1]
Why it matters A rash may be absent; life-threatening allergy is identified by organ compromise.
3
Use the emergency protocol
Give intramuscular epinephrine/adrenaline under the authorized pathway, support airway and oxygenation, and position safely without standing the patient. [1]
Why it matters Epinephrine addresses dangerous airway and circulatory effects; antihistamines do not replace it.
4
Prepare continued care
Arrange ordered fluids, repeat treatment and observation; report the exposure, symptoms and treatment times. [1]
Why it matters Symptoms can persist or recur, requiring monitored follow-up rather than immediate reassurance.

What to look for next

Track response and arrange ongoing observation and documented suspected triggers. Continuously review breathing, perfusion and response. Escalate ongoing compromise and arrange allergy documentation and follow-up after stabilization.

Avoid this shortcut

Do not substitute an antihistamine for treatment of airway or circulatory compromise. Do not wait for a rash, use antihistamines as sole emergency treatment or let a hypotensive person walk.

Why it matters Replacement alone cannot stop every source of bleeding or resolve medication-related risk.

What to look for next

Stay with the patient and track airway progression and perfusion during definitive treatment. Trend observations and loss after interventions. Escalate ongoing shock, respiratory change or a suspected transfusion reaction immediately.

Avoid this shortcut

Do not wait for a large drain volume or remove sutures outside your training and authorized emergency protocol. Do not wait for a laboratory result before responding to shock or independently select reversal drugs.

Assess work of breathing, respiratory rate, alertness, perfusion and oxygen saturation with a reliable signal. [1]
Why it matters A saturation number alone can miss exhaustion, carbon-dioxide retention or poor circulation.
3
Support and escalate
Use the prescribed oxygen target and delivery system. Call urgent respiratory help for increasing support needs, drowsiness or distress; prepare ordered blood gases. [1]
Why it matters Targeted oxygen treats low oxygen while blood gases and examination help guide ventilation decisions.
4
Check the equipment and response
Check supply, tubing, fit and connections; reassess symptoms and observations after changes and communicate the trend. [1]
Why it matters A disconnected system and worsening lung disease require different corrective actions.

What to look for next

Track oxygenation, work of breathing and ordered tests while the team determines the cause and treatment. Watch alertness, respiratory effort and oxygen needs rather than saturation alone. A tiring patient can become quieter while becoming less safe.

Avoid this shortcut

Do not assume every post-transfusion breathless episode needs the same diuretic response. Do not withhold lifesaving oxygen in critical illness or assume every person with COPD has the same target.

A clear way to hand it over

“I am calling about this new concern: pulmonary edema follows a large transfusion and fluid load. The key findings are __, starting at __. Baseline and relevant medicines/procedures are __. I have __. My assessment is __, and I need __ by __. Current response and outstanding actions are __.”

Use your facility's handover format; fill in the actual findings and times.

In plain English Ventilation moves air; oxygenation transfers oxygen into blood.

Electrolyte & rhythm safety

A severe potassium rise with a new arrhythmia

Extremely difficult

The situation

After complex surgery in a patient with kidney disease, the laboratory calls a critical potassium result and the ECG shows new conduction changes. Glucose is already low after earlier insulin.

What should catch your attention

Critical potassium plus ECG changes
Kidney disease
Existing low glucose

Your immediate priority

Activate the hyperkalemia emergency pathway and highlight glucose before additional prescribed insulin-based treatment.

Decision pathway · a learning summary, not a substitute for the full clinical plan

What the RN should do—and why

1
Respond to the situation first
Activate the hyperkalemia emergency pathway and highlight glucose before additional prescribed insulin-based treatment. [1]
Why it matters Severe potassium elevation can cause fatal rhythm changes, sometimes without dramatic symptoms.
2
Assess cardiac risk
Check symptoms, monitoring and ECG promptly; report the potassium result, kidney function and sample concerns without delaying care for an unstable patient. [1]
Why it matters Severe potassium elevation can cause fatal rhythm changes, sometimes without dramatic symptoms.
3
Support ordered stabilization
Prepare protocol-directed calcium when indicated and potassium-shifting or removal treatment; follow independent medicine checks. [1]
Why it matters Calcium protects the heart temporarily but does not remove potassium from the body.
4
Monitor treatment complications
Track repeat potassium and ECG, and glucose checks after insulin-based treatment, following the full monitoring period. [1]
Why it matters Potassium can rebound and treatment can cause delayed hypoglycemia.

What to look for next

Follow ECG, repeat potassium and glucose checks through the full treatment-monitoring period. Escalate ECG deterioration, recurrent high potassium or low glucose. Confirm the plan for potassium removal and medicine review.

Avoid this shortcut

Do not treat calcium as potassium removal or stop glucose observation after the first normal result. Do not assume a normal ECG excludes danger or that calcium has corrected the potassium level.

A clear way to hand it over

Anesthesia recovery & handover

The discharge score improves but the airway does not

Extremely difficult

The situation

A patient meets several numerical recovery-score items, but remains unusually drowsy and repeatedly obstructs their airway when unstimulated. Their planned destination has limited monitoring.

What should catch your attention

Repeated airway obstruction
Stimulated readings look better
Destination may be unsafe

Your immediate priority

Request anesthesia reassessment and a safer observation plan; communicate what happens when stimulation stops.

Decision pathway · a learning summary, not a substitute for the full clinical plan

What the RN should do—and why

1
Respond to the situation first
Request anesthesia reassessment and a safer observation plan; communicate what happens when stimulation stops. [1]
Why it matters Recovery risk depends on what happened during the procedure, not only the current vital signs.
2
Receive the real handover
Review procedure, anesthetic agents, airway events, medicines, loss, access and specific postoperative risks with the sending clinician. [1]
Why it matters Recovery risk depends on what happened during the procedure, not only the current vital signs.
3
Observe recovery actively
Assess airway patency, breathing, circulation, consciousness, temperature, pain and nausea according to the prescribed pathway. [1]
Why it matters Residual anesthesia and complications can become apparent after arrival.
4
Escalate and verify readiness
Seek anesthesia or surgical review for unexpected findings; use the approved discharge criteria and an individualized destination plan. [1]
Why it matters An acceptable summary score cannot override a serious unresolved clinical concern.

What to look for next

Confirm sustained independent airway safety and individualized discharge readiness. Review trends after medicines, position changes and transfer; verify the next monitoring and rescue plan.

Avoid this shortcut

Do not transfer on the score alone or assume the receiving ward can provide PACU-level rescue. Do not discharge only because a timer expires or a score improves while airway or circulation remains unsafe.

A clear way to hand it over

“I am calling about this new concern: the discharge score improves but the airway does not. The key findings are __, starting at __. Baseline and relevant medicines/procedures are __. I have __. My assessment is __, and I need __ by __. Current response and outstanding actions are __.”

Use your facility's handover format; fill in the actual findings and times.

In plain English PACU is the post-anesthesia care unit, where recovery is monitored after anesthesia.
